But the best Delve spells are restricted, you are warping your deck around a 3 mana planeswalker not named Dack Fayden, your deck would be incredibly vulnerable to Leyline of the Void and Rest in Peace, Bazaar makes this card really difficult to cast, Tasigur has diminishing returns in multiples and is vulnerable to Karakas, Gurmag Angler is embarassed by tokens, and Ashiok is 3 mana to go down a card and not impact the board in a meaningful way.
I mean, I did stream a UBw Bazaar Xeroxish list with JP Kohler and brew a Grixis deck that I tested but didn't stream, so it's not a crazy concept in my opinion. This card just doesn't add anything in any way, shape, or form to the idea. People always overestimate the effect of "hate" in evaluating cards. This is just another example.
